This invention has t0 do with pressure type irri- -gating apparatus and it is a general object of the invention to provide apparatus of this character` which is simple, convenient, safe and dependable.

It is desired under many and varied circumstances to provide apparatus to aid in irrigating or flushing cavities of the body, and it is not uncommon to employ medicaments of various types in the liquids used in such devices. A common form of -such apparatus is the ordinary fountain syringe wherein the liquid employed is causedto flow by reason of pressure gained by establishing ahead oi liquid. The head of liquid desired is4 usually gained by locating a reservoir of liquid at a suitable elevation. In using such a device it is common to introduce the desired medicament into the reservoir so that it is carried by the liquid handled thereby, Vbut there is no provision for regulating either the quantity or the character of` the medicament used and for this `reason the apparatus may be misused. Further, such apparatus in addition to being in many cases unsafe to use is cumbersome and lthe pressure generated is ordinarily limited.

`It is a general object of this invention to provide apparatus of the general character referred to in which the pressure delivering the iiushing liquid is developed in a generator that can be located wherever convenient and which need not be located at any yparticular elevation.

It is another object of the present invention to provide apparatus ofthe character referred` to which is safe to use even though a medium is employed for the positive generati-onv of pres?v sure. The apparatus that I have employed involves an open passage through which the liquid is delivered to the applicator and in use an increase of pressure in-the generator merely in.

creases the rate of ow of the liquid to the appli-.

c'ator. Y

. Another object of the invention is to provide apparatus of the general character referred-to which includes a material receptacle or carrier such as to receive and hold but a limited quan.

tity of material which acts in the apparatus to develop the pressure causing flow of the flushing liquid. With the construction that I have prov vided the generator is s-ectional, one section servf4 ing to carry the supply of liquid and the other to.

receive and hold the pressure generating mate- .f

l14 claims. (c1. 12s-224) rial in the liquid prior ready for use is merely dissipated.

Another object of the invention is to provide apparatus of the generalcharacter referred to involving'fewsimple parts that are inexpensiveof manufacture and very simple to manipulate. My construction involves parts'that are easily handled, stored and manipulated and the various parts are all such that they can be readily cleaned so that the apparatus may be quickly maintained in fit condition for use.

' The various objects and features of my invention will be fully understood-from the following detailed description oaf typical preferred forms and applications of the invention, throughout which description reference is made to the draw-` for application thereto, certain of the parts being shown in section. Fig. 3 is a detailed sectional' View taken as indicated by line 3-3 on Fig. 2,`

The apparatus that I have provided may be used -in various manners or for various purposes 1 and is generally useful for the irrigation of various cavities of the body, and it can be used to advantage Where it is desired to employ a medicant-in the liquid being used in the irrigation. My invention may be embodied in various forms,

to making the generator 3 and in the drawings I have shown it in two forms which are very much alike and Vwhich involve, generally, the same essential elements.

I n the form of the invention illustrated in Figs. 1 to 6 of the drawings the apparatus involves, generally, a generator A, a delivery conduit B handling uid from the generator, an applicator C carried on and supplied by the conduit, control means D controlling now vfrom thergenera-tortoi the conduit and preferably serving` as acoup'ling n or vertical position.

When the closure and body Y'are brought together the means l2 is engaged or set by simply rotating the body and closure relative to each other in the desired manner to bring the top end I8 of the body into sealing engagement with the washer l1 in the closure.

The duct B which I provide handles liquid VVfrom the generator and supplies it to the applicabetween the conduit and the generator, and a ,Y

material carrier or support E on one section of`4` the generator to be located within the. genera-tori' when Vthe sections thereof are assembled and the generator is in condition for'operation;

As the stem is moved downwardly in the shell the inlet port 4| gradually moves past the upper packing ring 32 establishing communication between the inlet port and the chamber X and when the control is fully open the inlet port 4| is in full communication with the chamber X, as shown in Fig. 4. It is to be understood of course th-at in practice I may provide more than one inlet port 4| and more than one outletport 43, as I have shown in the drawings.

In accordance with the broader principles of my invention the stem may be slid or shifted in the `shell in any suitable manner. However, I prefer to provide a means for operating or shiftingl the stem in the shell which means provides convenient control for the structure. In the case `illustrated in the drawings the upper end portion 31 ofY the stem is somewhat enlarged and continues downward into a counterbore 50 provided in the upper end portion of the shell. The exterior of the stem portion 31 is threaded so that this portion of the stem threads linto the counterbore 50 which is correspondingly threaded. An operating projection or handle is provided on the upper end portion of the Stem, that is on the upper end or projection portion 31, so that the operator may conveniently rotate the stem causing it to be either screwed up or down inthe shell as desired.

The carrier E provided to handle material for use in the apparatus may be a suitable receptacle or support, preferably carried by or from the closure In the form of the invention shown in Figs. 1 to 6 of the drawings the carrier E is a plate-like part or shelf 60 carried by the depending lower end portion 36 of the stem to be a suitable distance below the closure or below the lower end of the depending flange 2|) provided on the closure. The shelf-like support 60 may be a disc mounted concentric with the stem and in practice may be of limited diameter and located on the stern to be a limited distance below the closure so that only a limited amount of material can be arranged thereon at any one time.

The structure preferably includes a syphon tube. 65 depending from the stem as a continuation thereof` and proportioned so that itslower end which is open islocated immediately above the bottom I4 when the closure is in place on the cap and the stem is operated to its lowermost position. In the particular case illustrated the syphon tube is formed separate yfrom the stem and the shelf-like support 60 serves as a coupling or connecting means between the stem and the syphon tube. In this case bosses 65 are provided on the shelf-like support B0, the upper boss receiving the lower end of the stem while the upper end of the boss receives the end of the syphon tube. I

The stem 3| has a coupling portion 52 adjacent to and extending upwardly from the handle 5|. The coupling portion as shown in Fig. 1 of the drawings is a tubular continuation of the portion 31 and may have one or more annular ribs 53 to couple the conduit B to the control means D. When an ordinary conduit such as a rubber hose is employed the end 54 of the hose is stretched over the coupling portion 52 and conforms to the conguration of the coupling formed by the ribs.. By thus conforming the shape of the coupling portion the hose is securely attached to the means D and consequently to the generator A.

In using the apparatus a suitable quantity of liquid -such as water is placed in the body l0 preferably enough water to reach the indicating mark 24 and suitable material M is placed on the material support E or on the shelf in a manner such as is indicated in Fig. 2 of the drawings. The material M may vary widely in character or composition and in accordance with my inventionit involves essentially a material which when brought in contact with water generates pressure or is effervescent. For example, the material may include such materials as any carbonates or bicarbonate reacting with anacid, such as sodium bicarbonate, potassium bicarbonate, and such'an acid as citric or tartaric` acid. It is to be understood that the material M may include in addition to the `pressure generating element suitable medicaments as for instance disinfectants or soothing materials, all as may be desired.

With the body |0 filled to the desired level and the desired material located on the carrier E the generator is assembled by moving the body and closure relative to each other to locate the carrier within the generator above` the level of the liquid therein. The means |2 is operated to secure the closure on the body making the generator ready for use. With the desired applicator on the conduit B the apparatus is ready for use and to put it in operation it is merely necessary for the user to tilt the generator so that liquid from the body 0 thereof wets the material M. In practice the user may merely invert the generator momentarily in order to assure full wetting of the material M. With the material wetted the generating action proceeds and the user may operate the `meansD to allow the desired discharge of liquid through the conduit B for delivery to the applicator C. It will be apparent that by proper composition of the material M the device is safe to use and when in use so that liquid vis delivered to the applicator the control means D is necessarily open allowing flow so that excessive pressure cannot possibly be applied to the applicator.

In the `form of the invention illustrated in Figs. '7 to 10 the various parts are essentially the same as those above described except that the carrier E' for the material M' is somewhat different. In this form of the invention I provide a keyed engagement or relationship between the carrier and the material to be used so that only a specc or particular material can be handled by the carrier. This is desirable as it prevents unsuitable materials 'being used in the apparatus. In this form of the invention the carrier is located on the extension 3B of the stem but instead of being a shelf or plate-like element it is in the nature of a cross arm v8U preferably a narrow arm which may have slightly upturned ends 8| as shown in the drawings. Each body of material M' to be used in the apparatus is a wafer-like element provided with a central key opening 82 elongate in form and so shaped and proportioned as to accommodate the -cross arm 8D so that a wafer can be slid over the arm when positioned or related thereto as shown in Fig. 9. After having been moved up past the arm the wafer or material M' may be rotated to a position such as shown in Fig. 8 where it will be supported by the arm. It is to be understood that in practice one or more elements or wafers of material M may be used, as indicated in the drawings.` l
